I ,pplcation tiled December y20, 1918. Serial No. 267,622.

Be it known that l, ADOLPH United States, residin at Logansport, in the county of Cass and tate of Indiana, have invented certain new and nseful Improvements in Oiling Systems for Internal-Combustion Engines, of whlch the following isa specification.

This invention relates to improvements 1n' oiling systems for internal combustion engines and theY principal object thereof 1s the provision of 4such a system which 1s of slmple and .uniform construction and arrangement, whereby all of the operating parts of the mechanism are subject to the proper application of lubricant at all times.

.A further object of this invention is the provision of an internal combustion engine having a vertical driving shaft for operating the oil pump, water pump, generator, magneto, cam shaft and fan, this shaft being enclosed in a hollow post which cooperates with the crank casing and the engine casing to form agcomplete covering or casing. for

the various operatlng mechanisms,- having suitable conduits, pipes or passages provided to and from the oil pump to apply thelubrif cant at the proper places to insure adequate and efficient lubrication of the operating parts of the mechanism.

Further objects of this invention include improvements in details of construction and arrangement, whereby the above objects are accomplished. f

To the accomplishment of the foregoing and such other objects as may hereinafter appear my invention consists in the construction, combination and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof and which show, merely for the purpose of illustrative disclosure a preferred embodiment of my invention, it being expressly understood, however, that various changes may be made in practice within the scope of the claims withoutl digressing from my inventive idea.

Fig. 1 represents a front end elevation of a motor constructed to embody my inven-A tion, parts being shown in section and in dotted `lines to facilitate the disclosure.

Fig. 2 is a longitudinal and horizontal sectional view taken substantially on line 2-2 ofl Fig. 1.

Fig. 3 is a longitudinal and horizontal sec MoNsEN, a,

tional view taken substantially on line 3 3" of Fig. 1. l

Fig. 4 represents a horizontal sectional view taken substantially on line 4-4 o f Fig. 1, showing in detail theoil pump and the means for supporting the same.

Fig. 5 is a vertical sectional view on an enlarged scale on line 5,-5 of Fig. 2, showing the construction of the oil sump.

Referring now to meral 1 designates the crank case, 2 the cylinder and 3 the valve case whichis'formed on one side of the cylinder.- 4 designates a hollow post which is positioned on the front end of the motor and contains the operating tioned above the real bottom thereof, this false bottom 5 being provided with a series of depressions 6 adapted to receive and contain the oil for lubricating the cranks which operate therein. ll provide the webs or partitions 7 extending transversely across the crank case which have an intermediate opening 8 leading down through the false bottom linto the bottom proper of the crank case.

Positioned in one end of the bottom of the crank case is the oil sump which includes the strainer 9 held in place by the plug 10 and the supply tube 11 which is secured in a boss extending downwardly from the false bottom 5 of the crank case. This boss is provided with an opening 12 therethrough and the tube 13 is connected to vthe upper opening of this passage 12. This tube 13 passes along one side of the crank case and partially across one end of the samel in a slightly inclined direction, as at 14, leading to the passage 15 formed in the boss or projection 16 which is provided on the front end of the crank case, as shown. `@nthe other side of th crank case l provide the horizontally extending tube 17 which extends through the vloops or straps 18, discharge apertures 19 being provided therethrough. rFhis tube extends diagonally upward in the front ypart of the crank case, as at 20, to communicate withthe horizontal passage 21 through the boss-or projection 16 in the front end of the crank case. rlhe passage 15 communicates with the intake. side of the oil pump and the passage 21 communicates with the discharge side'of the oil pump.

At the rear end of tube 17, l connect the vertically extending tube 22 which passes the drawings, the nu-/ i'. boss .or projection 25 isprovided .withl the port 27 which vextends horizontally therethrough.

rPhe post 4 is hollow and extends vertically across the front end of the motor, as

shown in Fig. 1, and has mounted therein Thepost, ,4 is provided ,with su1table,en.

` vertical shaft.

the vertically arranged sha-ft 28. This shaft 28 is driven from the crank shaft 29 by means of theY spiral gear 30 of the crank shaft meshing with spiral gear 31 on the d'rhawiwng this,I gear 31 ofthe `vertical shaft also meshes with another spiral gear 32. on a short orstub shaft which'is arranged to operate the water circulatin shown). This vertical 4shaft is also provided with a. spiral gear 33 at or near the top thereof which has operative connection to drive the fan 34 and which also meshes with the spiral gear 35 o-n the front end of cam shaft 26. A similar gear connection, not shown, is provided at an intermediate part of shaft 28 for driving shaft 28 which operates the magneto and also the enerator.

larged parts to form casings or coverings for these various mechanisms in connection with the crank case and the piston and valve case construction, so that an oil tight casing is provided for the entire mechanism.

To the lower end of the post 4 the oil pump construction is detachably connected. ts casing comprises the two plate members 36 and 37, the latter being formed to provide` compartments to receive the cog or gear wheels l38 and .'39, which form the rotary gear p-ump.- Element38 is mounted to ro tate on the short o r stub shaft 40,- while element BQQis'secured'tothe short shaft 41, the

end vof which projects thro-ugh the plate 36 and'is reduced andsquared, as at 42, to fit into a correspondingly shaped socket 43 inI the lower endlof the vertical shaft 28. The pump including its casing is detachably connected to the lower e''d of the post by means o-f bolts as shown, so vthat the same may be readily attached' thereto and detached therefr'om.

'llhe passage 15 which is formed in the boss or projection 16 of the crank case communicates with a downwardly extending passage 44 provided in the lower part of the post 4, which passage 44 communicates with the upper end of the vert-ical port 45 provided in the upper plate 36 of the pump casing. This port 45 communicates with the longitudinally extending port or passage 46 As lshown in Fig. 2 of then" pump (not in the pump casing which has the right angle turn 47 to the inlet or intake side ofthe pump. The passage 21 in the boss or proA jection 16 of the crank case communicates with a similar passage 48 .provided in the post 4 which in turn communicates with the port 49 formed in the top plate 36 of the pump construction opposite the port 45, the port 49 communicating with the longitudinal passage 50 which has the right angle turn 51 leading to the exhaust or discharge side of the pump.

ln order to provide communication between the lower end of the post 4 andthe interior of the crank case, I form in the boss or projection 16 a plurality of ports or passages 52.

rlhe circulation of the oil is as follows. From, the oil sump the oil is drawn through the intake tube 11', tube `13, to passage l5 in the boss or projection 16, thence through passage 44 in the lower end of the post 4 to port 45 to passage 46 to the pump and thence through lpassage 50, port 49, passage v, 48,inv thelower end of the post to passage 2 1 in thelboss or projection 16, thence to tube 17 from which it is sprayed through the discharge openings 1 9 against the cranks. As statedv before, a certain amount of the oil which accumulates on the falsel bottom will pass through the openings 8 in the partition 7 directly tothe bottom of the crank case. .v 5.11v

Passing through the tubey 17 the oil is forced through tubes 22 and 23 into the valve casing* whereby the cam shaft and valves are lubricated. When it reaches -the level of the port or passage 27, which itis recalled, is formed "in the boss or extension 25 of the valve casing, the oil flows through the same downthrough the post 4 It then passes through the passages 52 provided in the boss or'extension v16 in the crank case,

back into the crank case, as is well under" stood. During this circuit all .of thev` i rariI ous o-perating parts and gears are subjected to the action of the oil, either,v directly or by being splashed or th'rownf' As the entire mechanism is enclosed in an oil tight casing there" is no1 leakage orwaste of the oil at any stage of its circuit. Thepump and the. strainer may both be readily removed for cleaning or other purposes'.
